It is likely not a problem with the monitor, because the lights indicate that the monitor is turned on.

It
may be a video card problem. Do you know if you have a video card, or
if it is integrated graphics? Check all of the connections from the
monitor to the computer. If you can connect the monitor to another
computer and it works, then it is definitely your computer.

Very,
very unlikely, but it could be that you're using a damaged cable. If
you have another one on hand, try it. If not, don't go and buy one
because this likely isn't the problem.

Another thing you could
try is turning the computer off, unplugging the power cable (going to
your computer), and hold the power button for about 30 seconds. Then
plug it in again and power it up.

I'm just guessing, but it could be that the resolution you are using on your MS-DOS monitor is not compliant with the new monitor you are trying to use. Check the supported resolutions of the monitor that you would like to use, and then make sure you set that resolution before switching monitors.
